What's on the Ohio Fire Alarm Exam: Topic Breakdown and Study Plan
The Ohio SFM Fire Alarm & Detection Equipment exam is a 100-question, closed-book, 120-minute PSI-administered exam with a 70% passing score. The reference list is short but deep: NFPA 72 (2022 edition), Ohio Fire Code §918 (OAC 1301:7-7-09), and Ohio Building Code Chapter 9.
This post breaks down the topic areas, what the references actually cover, and how to structure a study plan that respects the closed-book reality.
Exam format at a glance
| Spec | Value |
|---|---|
| Questions | 100 |
| Time | 120 minutes |
| Format | Closed book, multiple choice |
| Passing score | 70% (70 of 100 correct) |
| Eligibility window | 90 days after SFM approval |
| Retests | Unlimited within window |
The closed-book format is the defining feature. Most SFM categories follow the same structure, but the Fire Alarm category leans harder on NFPA 72 numerical recall — battery sizing, spacing tables, wiring class definitions — than the other detection categories. You can't look anything up. Plan accordingly.
NFPA 72 (2022) — what's actually tested
The bulk of the exam comes from NFPA 72 (2022), and a handful of chapters dominate. Closed-book means you need these chapters memorized, not just familiar.
Chapter 17 — Initiating Devices. The largest single source of questions. Smoke detector spacing (30-foot rule, beam spacing, smooth vs. joist ceilings), heat detector classifications (fixed temp vs. rate-of-rise), spot-type vs. line-type, manual pull station mounting heights, duct detector requirements. Memorize the spacing tables.
Chapter 18 — Notification Appliances. Candela ratings for strobes, mounting heights (80" AFF minimum, 96" max from ceiling), audibility requirements (15 dBA above ambient, 5 dBA above maximum sound level for 60 seconds), sync requirements for strobes in the same field of view.
Chapter 23 — Protected Premises / Wiring & Circuits. Class A vs. Class B vs. Class N circuit definitions, survivability levels, pathway designations (Pathway Class X / NPLFA distinctions). This chapter is dense; closed-book candidates routinely lose points here.
Chapter 14 — Inspection, Testing, and Maintenance. ITM frequencies (annual, semi-annual, monthly, weekly), what gets tested and how, sensitivity testing rules, documentation requirements.
Chapter 29 — Single- and Multiple-Station Alarms / Household. Required smoke alarm locations in dwelling units, interconnection rules, power requirements.
Ohio Fire Code §918 and OBC Ch. 9
These are the short-form Ohio-specific references — and the ones candidates most commonly under-prepare for.
OFC §918 (OAC 1301:7-7-09) is administrative: company association requirements, certification categories, reciprocity rules, the SFM's authority to revoke. You'll see a handful of questions here that aren't difficult if you've read the section but are nearly impossible if you haven't.
OBC Chapter 9 is the Ohio Building Code's fire-protection chapter — occupancy classifications, when a fire alarm system is required by occupancy type, sprinkler-system tie-in requirements. Expect questions of the form "in what occupancy is a manual fire alarm system required at X occupant load." There's no way to reason this from first principles; you either know the threshold or you don't.
Topic-by-topic study plan
A 4-week plan that respects the closed-book constraint:
| Week | Focus | NFPA 72 / Code |
|---|---|---|
| 1 | Initiating devices, smoke + heat spacing | Ch. 17 |
| 2 | Notification, wiring, circuits | Ch. 18, Ch. 23 |
| 3 | ITM, household, fundamentals | Ch. 14, Ch. 29, Ch. 10 |
| 4 | Ohio code layer + full-length practice | OFC §918, OBC Ch. 9 |
The first three weeks are reading + flashcards. The fourth is the most important: full-length practice tests under closed-book conditions, then drilling whichever topic area scored lowest. Don't skip Week 4 thinking you can "review the day before" — closed-book exams punish that strategy.
If you have less time, prioritize Chapters 17, 18, and 23 of NFPA 72 plus OBC Chapter 9 occupancy classifications. Those four areas alone account for the majority of test items.
What to do next
The Ohio SFM Fire Alarm exam doesn't reward shallow familiarity. The closed-book format means every reference table, every chapter section, every Ohio-specific rule has to be in your head on test day.
Our Ohio Fire Alarm practice tests cover the exact NFPA 72 (2022) chapter mix above plus the Ohio code layer (OFC §918, OBC Ch. 9), with questions tagged by chapter so you can drill weak areas. Plans include detailed answer explanations with codebook references.
